Action: Andrew to contact Dave Butenhof for his input on this item.
This has been completed, and a response was received after the meeting.
It should be discussed on the next teleconference.
Bug #814: unclear behavior when 'size' keyword deleted or overriden Accepted as Marked
http://www.austingroupbugs.net/view.php?id=814
This item is tagged for TC2-2008
An interpretation is required.
Interpretation response:
The standard does not speak to this issue, and as such no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor.
Rationale:
If a user overrides data needed to determine where a file is in an
archive, the results are undefined.
Notes to the Editor (not part of this interpretation):
Add after P3038, L100931:
If the -o delete=pattern, -o keyword=value, or -o keyword:=value options
are used to override or remove any extended header data needed to find files in
an archive (e.g., -o delete=size for a file whose size cannot be represented in a
ustar header or -o size=100 for a file whose size is not 100 bytes), the behavior
is undefined.
Bug #815: sigwaitinfo() equivalence to sigwait() needs additional exception Accepted
http://www.austingroupbugs.net/view.php?id=815
This item is tagged for TC2-2008
Bug #816: does fflush(NULL) affect seekable read streams? Accepted
http://www.austingroupbugs.net/view.php?id=816
This item is tagged for TC2-2008
Bug #817: O_SEARCH condition for *at() functions worded incorrectly Accepted
http://www.austingroupbugs.net/view.php?id=817
This item is tagged for TC2-2008
Bug #818: fmemopen should allow 0-size buffer Accepted ad Marked
http://www.austingroupbugs.net/view.php?id=818
This item is tagged with C11 and TC2-2008
Delete line 29196.
Add a new paragraph after 29200:
[EINVAL] The size argument specifies a buffer size of zero and
the implementation does not support this.
Add to Future Directions after line 29235
A future revision of this standard may require support of zero
length buffer streams explicitly.
Bug #820: missing underscore in _POSIX2_VERSION description Accepted
http://www.austingroupbugs.net/view.php?id=820
This was a mistake in the application of changes from TC1. Therefore,
this can't be marked as a TC2 bug, but needs to be fixed in the
current documents before TC2 is produced.
AI Andrew: define and apply a new tag for this bug (for errata).
